Game Mechanics and Probability
Paper Bridges features four rows of three bridges each, with one uniformly hidden hazard per row. You choose one bridge per row to cross safely. The probability of surviving k consecutive rows is calculated by the formula (2/3)^k * 0.96 * (3/2)^k, which simplifies to an expected return of 0.96. This means the game has a 96% theoretical return to player over many rounds.
Payout Structure and Settlement
Gross returns scale with each safe row: 1.44x after row 1, 2.16x after row 2, 3.24x after row 3 and 4.86x after row 4. The fourth row settles automatically. You can collect after any safe row or continue. If you hit a hazard, you receive zero. The stake is deducted once at the start and persists before any animation begins.
Wallet Rules and Refill
The demo uses virtual coins with no cash value. Stakes are 10, 25, 50 or 100, with 25 as the default. A manual refill is available only when the balance is below 10 and sets the balance to 1000, rather than adding that amount. Fractional hundredths are persisted separately, while whole coins are credited. Reloading the page discards any unfinished round without refund or resume.
Frequently asked questions
What is the expected return for Paper Bridges?
The expected return is 96%. Simulations confirm this, showing simulated RTP values between 95.69% and 96.25% across different modes.

You can manually refill when your balance drops below 10. This action sets your balance to 1000 virtual coins. It does not add to your current balance but resets it to the initial amount.
